How to advertise properly for your shop ?

Hello fellow Redditors and Etsy sellers ! Hope you're all doing well + I am sorry if someone has made a similar post.

I opened my shop a few months ago and I am selling digital products, I don't have a lot of sales because I know this branch is quite saturated but it's OK, let's say its the beggining (FYI : I am selling emotes and badges for streaming platforms). However I think that I don't get a lot of visitors and I was wondering how I could advertise for my shop ? What could work well ? I am pretty much new to this world and I only use twitter and discord (but I don't have a lot of visibility). Some friends suggested me insta reels, tiktok or even pinterest but I don't even know what kind of content I can post on these apps as I am not really familiar with them. I don't know where to start from and I could use some advice with your experience if you have some tips to share, I will be glad to hear from you guys.

Here's my shop if you want to take a look ( and give me your feedback if you feel like doing so ) https://yuzulemonade.etsy.com
